Springboot Redis 如何缓存 OAuth2Authorization ？

Question

版本

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-oauth2-authorization-server</artifactId>
            <version>3.1.0</version>
        </dependency>

RedisTemplate配置

    @Bean(name = "redisTemplate")
    @ConditionalOnClass(RedisOperations.class)
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory factory) {
        RedisKeyStringSerializer keyStringSerializer = new RedisKeyStringSerializer(keyPrefix);
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        // Key 采用String 的序列化方式
        template.setKeySerializer(keyStringSerializer);
        // hash 的 key 也采用 String 的序列化方式
        template.setHashKeySerializer(keyStringSerializer);
        // value 序列化方式采用 jackson
        template.setValueSerializer(RedisSerializer.json());
        // hash的value序列化方式采用jackson
        template.setHashValueSerializer(RedisSerializer.json());
        template.afterPropertiesSet();
        return template;
    }

OAuth2Authorization把这个对象缓存进了redis, 序列化不出来，它里面的AuthorizationGrantType没提供无参构造.

如果将Redis配置成RedisSerializer.java()就会导致不好查看，不知道还没有其他的解决办法。

Answer 1

public abstract class AuthorizationGrantTypeMixin {
    @JsonCreator
    public AuthorizationGrantTypeMixin(@JsonProperty("value") String value) { }
}

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.addMixIn(AuthorizationGrantType.class, AuthorizationGrantTypeMixin.class);

RedisSerializer<Object> serializer = new GenericJackson2JsonRedisSerializer(objectMapper);
template.setDefaultSerializer(serializer);
